I have been experiencing frontend freezes on 0.19-fixes last compiled a
couple of days ago. I have been having the same problem with all releases of
0.19 including the precompiled ones from atrpms. My system is running FC2
keept up to date thru atrpms. I am starting to wonder if I need to upgrade
my system from FC2. Below is a backtrace from the latest freeze along with
the output of top. Any of you guru's see anything useful here?
